What's the base rank of the weapon? I understand it ranks up with you, but to price it correctly it needs a base rank. SO far with just an A-Rank ability it should cost you 2,500

So I made it start off with rank D,lol I hope I got the price right. Uhm How many words Do I need to type in order to rank it up?

The ability seems more like a B or C rank ability. And for leveling swords I would say... Either they rank up with you or you could purchase the next rank prematurely. Either way though you'd need to pay for the weapons rank and actually D ranks arent allowed special abilities soooo what i suggest is...

Just purchase a higher ranking one and then pay the price difference whenever you want to rank it up.

ahhh I see thanks. I'll just have it rank up with me when I rank up, I also decided to make it an A rank weapon. Anything else I need to change?

I approve
